SEALING DEVICE.

Application filed February 25, 19 118. Serial No. 218,978.

To all whom z't may concern:

Be it known that I, ARTHUR G. Gr. GUEN- THER, a citizen of the United'States, residing at Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Sealing De-vices, of which the following is a specification.

This invention relates to sealin devices for sealing cartons or the likehipping cartons in the form of boxes of cardboard and similar material are well known. These cartons frequently have fiap covers of various kinds which are folded down on one face of the carton, `the'carton being subsequently reinforced and secured if necessary as by bein bound with metal strap near each end. ilfering has been a very common incidentv in the shipping of cartons of this character, it being generally possible for a person to slip his hand through the joint in the fiaps in between the reinforcing bands and remove a portion of the contents of the carton without detection.

It is an object of the invention to produce a sealiiig device for cartons by Which the same may be sealed in such a way that pilfering is impossible without detection. In suitable instances, the sealing devices may be used as the only securing means for the carton, the bands being omitted. In the strongest form of package, however, bands or bindiiigs will be supplied, one near each end of the carton, and the sealing means placed in between the bands to seal the fiaps of the carton and prevent pilfering.

In the drawings f Fig. 1 is a erspective view of one of the (io-operating astener devices made accordino' to my invention;

ig. 2 is a perspective view of the other device;

Fig- 3 is a perspective view showing these devices as applied to a carton, fragments of the fiaps of which are shown in the drawmgs;-

Fig. 4 is a perspective view of a carton having a plurality of sealing devices applied thereon.

In the drawings, 1 represents in general a box or carton having two top fiaps 2 and 3 which are folded down as clearly shown, in Fig. 4, on the top of the carton. My sealin devices are shown in Figs. 1 and 2. The evice of Fig. 1 comprises a metal fastener, referred to generally as 4, having prongs 5 at one end thereof and an extending tongue 6. The prongs 5 are shown in dotted lines as stamped out of the metal, and in full lines as bent up to be thrust through and bent under the fiap of the carton. The co-operating device is shown in Fig: 2 and comprises a sheet metal device 7 having prongs 8 at one end thereof and at the other end a sleeve 9, both formed by bending the portions stamped out of the flat blank and shown in dotted lines in Fig. 2 into the form shown in full lines in the same figure. In applying these devices to a carton, the prongs 5 and 8, after being bent at right angles to the body of the fastener device and forced through the cardboard orother material of the carton, being clenched thereunder as indicated in dotted lines in Fig. 3. 'These devices are aligned upon the opposite fiaps of the carton which it is desired to seal, and when the carton fiaps are folded down upon the face of the carton the tongue 6 is slipped through the sleeve 9, which in preferred forin is placed with the slot downwardly, after which a criinping tool is applied to the sleeve 9 and tongue 6 enclosed therein, to simultaneously crimp sleeve and tongues together as shown at 11. As many of these seals as desired inay be placed across a joint in the carton and will absolutely prevent pilferin without detection.

It will be noted that the devices are extremely simple, the forms shown in Fig. 1 and Fio'. 2 above being capable of being stampe from thin sheet metal, and the application of these devices to the cartons is also simple, it being only necessary to force the prongs through the material of the carton and clench them on the under side.

Fig. 4 shows a carton sealed entirely by means of these devices. It is of course to be understood that where shipping conditions require it, reinforcing bands or other binclers may be added to the carton, preferably one near either end, so as to properly reinforce the same, in which event the sealing devices shown in Fig. 4 will serve to prevent pilfering and assist in maintainin the carton secure.

aving now described my invention, I

olaini:-

1. A seal for cartons comprising a metallic' fastener secured upon a flap of the carton, a secondmetallic fastener secured upon another ortion of the carton, a tongue on one of the fasteners, a sleeve on the other fastener for the reception of the tongue, said tongue being inserted within said sleeve and'the sleeve and ton ue being crimped together into locked and sealed'relation, the portion of said tonfgue which is nserted in said sleeve' being o uniform width prior to crimping.

2. As an article of manufacture, a fastener element comprising a metal strip hav- -ing prongs at one end, whereby it may be secured to a carton or -the like, and a tongue at the other end, and a sleeve formed on said tongue, adjacent the free end thereof and adapted to be crinped with an enclosed strip into a tension resisting sealed joint.

3. A fibre carton having oppositely disposed fiaps, a plurality of tongues secured to each of said flaps extending in opposite directions in overlapping relation and masara aligned in pairs, a sleeve formed integral with one of the tongues of each pair and adapted to receive the other tongue of the air, the sleeve and tongue of each pair ing crimped together to provide a sealed tension resisting joint connecting said tongues.

4. A fibre carton having oppositely disposed flaps, a tongue secured to each of said fiaps, said tongues extending in opposite directions in aligned, overlapping relation, a

'sleeve formed integral with one of said tongues and adapted to receive the other said tongue, said sleeve and tongue being longitudnally crimped to provide a taut band connecting said flaps with the edges of the crimped portions disposed upon the i inner side of said band. I

In testimony whereof, I have signed my name to this specification. v
